Abstract
The utility model relates to an air valve oil seal pull-off force measurement apparatus. The apparatus comprises a threaded stud, a cavity structure, an air valve conduit. The upper part of the threaded stud is provided with a connection hole, while the lower part of the threaded stud is provided with external threads. In the cavity structure, large, intermediate, and small circular hole cavities are sequentially arranged from the top to the bottom, and the three circular hole cavities share the same axle center and are cut through sequentially. The upper hole cavity is provided with internal threads and is connected with the threaded stud. The height of the middle hole cavity is greater than that of a tested air valve oil seal, and the internal diameter of the middle hole cavity is dynamically fitted with the external diameter of the tested air valve oil seal. The internal diameter of the lower hole cavity is dynamically fitted with the external diameter of the air valve conduit. An oil seal metal framework is clamped and supported by a step between the middle hole cavity and the lower hole cavity. The upper part of the air valve conduit is assembled and fitted with a sealing face in the inner side of the air valve oil seal, while the lower part of the air valve conduit penetrates through the lower hole cavity. The apparatus is capable of measuring the maximum pull-off force of the air valve oil seal and the air valve conduit and effectively preventing the air valve oil seal from dropping during the actual installation process.
Description
Technical field
The utility model relates to a kind of valve oil seal pull-out force measurement mechanism.
Background technology
Domestic valve oil seal product design in the past, be all according to normative reference design and Experience Design, and control by the compressibility of counting yield the magnitude of interference that product inwall coordinates with valve guide bushing, and the negative pressure of the working environment of product is little, therefore as long as even if product is oil-proof qualified after coordinating with conduit, appearance along with modern turbine engine, it is harsher that the working condition of product also becomes, the working environment pressure of some product has even reached negative pressure 280KPa, in this case, even if product is oil-proof qualified after not only just coordinating with conduit, must hold out against the situation that product under the condition of negative pressure when working environment does not come off with conduit.
Summary of the invention
The purpose of this utility model is to provide a kind of valve oil seal pull-out force measurement mechanism, can testing product and maximum pull-out force after the coordinating of conduit by this device, thus effectively control the fault that product comes off from engine.
The utility model, comprises threaded column, cavity body structure and valve guide bushing, and the top in threaded column, is provided with connecting hole, and the bottom in threaded column, is provided with external thread, in cavity body structure, be provided with successively large from top to bottom, in, little three sections of circular hole chambeies, three sections of circular hole chambeies have identical axle center and connect successively, wherein, epimere vestibule is provided with internal thread, internal thread is connected cooperation with the external thread of threaded column bottom, the height of stage casing vestibule is greater than the height of tested valve oil seal, the internal diameter of stage casing vestibule coordinates with the external diameter of tested valve oil seal is moving, the internal diameter of hypomere vestibule coordinates with the external diameter of valve guide bushing is moving, oil seal metal frame card holder is on the step between stage casing vestibule and hypomere vestibule, the top of valve guide bushing coordinates with valve oil seal inner seal face, the bottom of valve guide bushing is through described hypomere vestibule.
The utility model, tool has the following advantages: simple in structure, easy to use, can use electronic tensile machine directly to measure the maximum pull-out force that valve oil seal product coordinates with conduit, thereby effectively prevent the problem that the product later stage comes off.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 10, threaded column 11, connecting hole 12, external thread 20, cavity body structure 21, internal thread 22, stage casing vestibule 23, hypomere vestibule 30, tested valve oil seal 31, oil sealing inner seal face 32, oil seal metal frame 40, valve guide bushing.
Embodiment
With reference to Fig. 1, a kind of valve oil seal pull-out force measurement mechanism, comprises threaded column 10, cavity body structure 20 and valve guide bushing 40, on the top of threaded column 10, is provided with connecting hole 11, in the bottom of threaded column 10, is provided with external thread 12, in cavity body structure 20, be provided with successively large from top to bottom, in, little three sections of circular hole chambeies, three sections of circular hole chambeies have identical axle center and connect successively, wherein, epimere vestibule is provided with internal thread 21, internal thread 21 is connected cooperation with the external thread 12 of threaded column 10 bottoms, the height of stage casing vestibule 22 is greater than the height of tested valve oil seal 30, the internal diameter of stage casing vestibule 22 moves and coordinates with the external diameter of tested valve oil seal 30, the internal diameter of hypomere vestibule 23 moves and coordinates with the external diameter of valve guide bushing 40, oil seal metal frame 31 card holders are on the step between stage casing vestibule 22 and hypomere vestibule 23, the top of valve guide bushing 40 coordinates with valve oil seal inner seal face, the bottom of valve guide bushing 40 is through described hypomere vestibule 23.
During measurement, first valve oil seal 30 and valve guide bushing 40 are assembled to (valve guide bushing 40 is and the actual concrete parts that use on engine of valve oil seal 30), then put it in cavity body structure 20 and make valve guide bushing 40 through hypomere vestibule 23, by borded pile 10 spinnings on the internal thread 21 of cavity body structure 20, now, oil seal metal frame 31 card holders are on the step between stage casing vestibule 22 and hypomere vestibule 23, then respectively threaded column 10 and valve guide bushing 40 are fixedly connected on the relevant position of electronic tensile machine, and control electronic tensile machine and respectively threaded column 10 and valve guide bushing 40 are outwards stretched, when valve guide bushing 40 departs from valve oil seal 30, reading on electronic tensile machine is the maximum pull-out force of valve oil seal 30.
